The invention provides a nanostructure including an anodized film including nanoholes. The anodized film is formed on a substrate having a surface including at least one material selected from the group consisting of semiconductors, noble metals, Mn, Fe, Co, Ni, Cu and carbon. The nanoholes are cut completely through the anodized film from the surface of the anodized film to the surface of the substrate. The nanoholes have a first diameter at the surface of the anodized film and a second diameter at the surface of the substrate. The nanoholes are characterized in that either a constriction exists at a location between the surface of the anodized film and the surface of the substrate, or the second diameter is greater than the first diameter.

A method of producing a structure having narrow pores includes a first step of bringing pore-guiding members into contact with upper and lower surfaces of a member comprising aluminum as a principal ingredient and a second step of anodizing the member comprising aluminum as the principal ingredient to form narrow pores. The pore-guiding members contain the same material as a principal ingredient. The second step includes preferably a step of transforming the member comprising aluminum as the principal ingredient into a porous body comprising alumina having narrow pores oriented substantially parallel to the interfaces between the pore-guiding members and the member comprising aluminum as the principal ingredient.

A method of manufacturing a structure with pores which are formed by anodic oxidation and whose layout, pitch, position, direction, shape and the like can be controlled. The method includes the steps of: disposing a lamination film on a substrate, the lamination film being made of insulating layers and a layer to be anodically oxidized and containing aluminum as a main composition; and performing anodic oxidation starting from an end surface of the lamination film to form a plurality of pores having an axis substantially parallel to a surface of the substrate, wherein the layer to be anodically oxidized is sandwiched between the insulating layers, and a projected pattern substantially parallel to the axis of the pore is formed on at least one of the insulating layers at positions between the pores.
